I have been signed off sick but my employer has not paid me

I was verbally told that I was being made redundant about 6 weeks ago. However the same evening I became ill, physically throwing up. I also suffer with Lupus and at the moment my hair is falling out considerably. My doctor has now signed me off until 4th Dec 2008. I had sent medical certs to employer but have had no response. I was suppose to be paid yesterday and I have not received any monies from employer! I sent a grievance in stating 1. had not recieved notice of redundancy or redundancy package, 2. have not received any letter terminating my employment so I am still employed by them. 3. I have never been invited in for a consultation meeting regarding the redundancy issues or to discuss my time off sick with depression and lupus and 4. I had not recieved any salary this month. I have given them until 9 Dec to respond and said if they did not I shall assume that I am expected to return to work and await confirmation of this and the date they want me to return. I am so annoyed because I cannot even go to the Benefits Agency to get my rent and council tax paid because I have no proof that I am now unemployed and did not receieve any salary this month. What else can I do? I am so distraught with worry because I have all my bills to pay and jobs are so hard to come by due the recession. I HAVE BEEEN EMPLOYED FOR 2.5 YEARS
